The quality of low voltage and middle voltage
installations is very important. The presence
of distortions such as harmonics can have a
severe influence on this quality. The European
regulation EN 50160 is one of the most
important regulations for measurements of
LV-installations. The essential values for
LV-installations are subscribed in this regulation.
The Power Quality Analyser PQA6600 is a
complete instrument engineered for analysis of
the quality of a three-phase system. Basically,
the PQA6600 is equal to the PHA3300, but
more functions have been included.
The PQA6600 has the following extra
features:
- Waveforms measurement
- Fast logging
- Transients measurement
- Flicker analysis
Using these functions identifying the
distortions in engines, computers and other
appliances is easy.
Depending on the value to be measured,
several accessories and probes can be used.
For measuring currents, several current clamp
adapters are available (see pages 33-34, chapter
Current Clamp Adapters). With these adapters,
a complete three-phase installation can be
measured and analysed up to 3000 Amps.
In order to measure and analyse a
LV-installation, according to the EN50160,
two Power Analysers are available within the
Nieaf Instruments program:
The Power Harmonics Analyser PHA3300
is a portable instrument for measuring and
analysing single- and three phase systems.
Also irregular or interrupted voltage supplies
can be detected or recorded. Data recording
is one of the most relevant functions of the
instrument. After a period of statistical or
periodical analysis, the data can be transferred
to the PC software easily.
For optimal analyses of the measured values,
the included Windows software can be used.
This software can be used for storing the test
data and to make several reports and graphical
displays, all according to the EN50160
regulation. Obviously, the data and the reports
can be stored and printed. For report
modification into a customised report, the data
and reports can be exported to .xls-files.

POWER ANALYSERS
SPECIAL FUNCTIONS FOR POWER QUALITY ANALYSER
Special tools enable a detailed, time domain based signal analysis. They represent a powerful, modern troubleshooting tool for solving all kinds of problems,
which are appearing in power distribution systems. The user can choose between three modes, differing in terms of sampling speed, trigger possibilities
and recording time.
WAVEFORMS
Recording of voltages and currents with 128
samples/period. Half period RMS values of
recorded quantities are also calculated and
shown in this mode. Best suited for:
- monitoring of switching phenomena,
- locating of noise and disturbance sources,
- defining disturbance type,
- locating excessive harmonics sources.
Typical problems that can be solved by
WAVEFORM analysis: capacitor banks switch
over, transformer overheating, UPS problems,
SMPS failures, etc.
FAST LOGGING
Recording of half period RMS voltage and
currents values. Recommended when record
length is critical and signal’s details are not of
importance. Best suited for:
- observing start up and inrush events,
- locating impedance problems,
- long term analysing of unstable mains.
Typical problems that can be solved with FAST
LOGGING analysis: too high inrush currents of
large motors, undersized fuses and installation
wiring, too weak voltage source, etc.
TRANSIENTS
The recording mode with fastest sampling rate
that the instrument can provide. Up to 50 kHz
transients detect ability in this mode. Best
suited for:
- monitoring atmospheric discharging,
- analysing switching problems,
- detailed analysing of high frequency noise
and notching.
Typical problems that can be solved with
TRANSIENT analysis: frequency noise, voltage
spikes caused by switching of capacitor banks,
etc.
EN 50160
Usually the NET quality is tested according the EN 50160 standard.
The PQA6600 can be set up to perform a basic measurement
according this standard. Results of such measurements are an
automatically generated report with good/fault indication.
REPORT
The (included) software contains a large number of possibilities for
reproduction of graphics for several measurements. It is also possible to
generate a complete EN50160 report. Graphics, reports and measurement
values can transferred to Excel or Word for further processing.
The PHA3300 and PQA 6600 perform tests according the following standards: EN 61000-4, EN 61000-7, EN 61000-11.
The instruments are produced according EN61010-1 (safety), EN50081-1 and EN 6100-6-1 (EMC) standards.
